Greg Palast has some interesting things to say about the resignations of Rove and Gonzales (snippet):

"....So what is most frightening is not the resignation of Alberto Gonzales, the Pinocchio of prosecutorial misconduct, but the resignation of Karl Rove. Because New Mexico 2004 was just the testing ground for the roll-out of the “ID” attack planned for 2008. And Rove who three decades ago cut his political fangs as chief of the Nixon Youth, is ready to roll. To say Rove left his White House job under a cloud is nonsense. He just went into free-agent status, an electoral hitman ready to jump on the next GOP nominee’s black-ops squad. The fact that Rove’s venomous assistant, Tim Griffin, was set up to work for the campaign Fred Thompson, is a sign that the Lord Voldemort of vote suppression is preparing to practice his Dark Arts in ‘08. It was Rove who convinced Bush to fire upright prosecutors and replace them with Rove-bots ready to strike out at fraudulent (i.e. Democratic) voters."
